Which of the following has the greatest mass? The mole is used in chemistry to represent [latex]6.022\times {10}^{23}[/latex] of something, but it can be difficult to conceptualize such a large number. To do this, we simply need to multiply the mass of one marshmallow by the Avogadro's number. Therefore, even though marshmallows have a greater volume, lead is significantly heavier. The result is in agreement with our expectations as noted above, around 0.04 g Ar. four moles of hydrogen. lead has a density of 11340 kg/m3, while marshmallows have a density of only 50-60 kg/m3. No. Learn More: Why do companies lower product prices and offer free samples? Which part of a chemical formula indicates the number of copies of molecules or compounds? When it comes to lead, it is important to note that its weight makes up for what it lacks in volume. One mole of glycine, C2H5O2N, contains 2 moles of carbon, 5 moles of hydrogen, 2 moles of oxygen, and 1 mole of nitrogen: The provided mass of glycine (~28 g) is a bit more than one-third the molar mass (~75 g/mol), so we would expect the computed result to be a bit greater than one-third of a mole (~0.33 mol). Which one of the samples has the largest mass? nceptual (A) 1 mole of marshmallows (B) 1 mole of Pb (lead) atoms (C) 1 mole of CO2 (carbon dioxide) molecules (D) All of these. This means that, for the same volume, lead is much denser than marshmallows. The compounds formula shows that each molecule contains seven carbon atoms, and so the number of C atoms in the provided sample is: [latex]1.31\times {10}^{20}{\text{C}}_{7}{\text{H}}_{5}{\text{NO}}_{3}\text{S molecules}\left(\frac{7\text{C atoms}}{1{\text{C}}_{7}{\text{H}}_{5}{\text{NO}}_{3}\text{S molecule}}\right)=9.20\times {10}^{21}\text{C atoms}[/latex].
